1210W2F100LT5E 产品概述
一、产品简介
1210W2F100LT5E 为 UNI-ROYAL（厚声）出品的贴片低阻值厚膜电阻，封装为 1210（英制），阻值 0.1Ω（100mΩ），精度 ±1%，额定功率 500mW，工作电压 200V，温度系数（TCR）±800ppm/℃，工作温度范围 -55℃ ~ +155℃。该型号专为电流检测与功率控制场景设计，兼顾体积、耐压与散热性能。
二、主要性能参数
- 阻值：0.1Ω（100mΩ）
- 精度：±1%
- 额定功率：0.5W（在额定参考环境下）
- 最大工作电压：200V
- 温度系数：±800ppm/℃
- 工作温度：-55℃ ~ +155℃
- 封装：1210（常见用于较大功耗的贴片电阻）
三、典型应用场景
适用于电源管理与测量类电路，包括：
- 电流检测与分流（电流感测、过流保护）
- 电池管理系统（BMS）电流监测
- 开关电源与稳压模块的电流采样
- LED 驱动、电机驱动与功率放大器中的低阻电流路径
四、选型与电路布局建议
- 对于精确电流测量，建议采用四线（Kelvin）测量法或在布局上尽量缩短测量回路，以降低接触与焊盘电阻带来的误差。
- 1210 尺寸允许较大散热路径，建议在 PCB 上使用加厚铜箔、扩大焊盘并辅以散热铜层或过孔，提升功率耗散能力。
- 考虑 TCR 为 ±800ppm/℃，对温度敏感的应用应在系统设计中加入温度补偿或校准策略。
- 若长期在高温环境工作，应按制造商资料对功率做适当降额处理，并考虑额定温度下的热阻与自热效应。
五、可靠性与焊接建议
- 使用与制造商推荐相符的回流焊工艺，避免超温或长时间高温曝露以保持阻值稳定性。
- 焊盘设计要避免过薄的焊料层和不对称焊盘，以免引起应力导致电阻漂移或机械破坏。
- 对关键计量点建议在调试阶段进行长期老化与温度循环试验，验证稳定性与漂移。
六、采购与使用提示
选择 1210W2F100LT5E 时，建议索取并参照 UNI-ROYAL 的详细数据手册，确认额定功率的参考环境（如参考温度）、封装尺寸公差及焊接曲线。对精度和温漂要求较高的场合，可考虑与更低 TCR 或金属合金材质的电阻进行比对。若需批量采购，请标明阻值、精度、工作温度与包装形式以确保交付一致性。

Product sourcing intelligence
Model, package, availability, and BOM fit reviewed before quotation.
WMSIC turns product data, package visuals, BOM context, and sourcing signals into practical RFQ notes for buyers.
BOM matching & alternatives
BOM lines are compared by package, parameters, quantity, and workable alternatives for cleaner sourcing decisions.
Sourcing availability signal
Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.
Buyer sourcing scenarios
Examples of how common component sourcing requests are organized.
Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.
The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.
A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.
The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.
Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.
Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.
When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.
Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.
The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.
